pentene

I ask another chemistry teacher and he too said this is correct either 1,pentene, or pentene.

As an example, the saturation of the olefin pentene can be simply expressed as:

The physical state depends on molecular mass (gases from ethene to butene - liquids from pentene onwards).

Other binding in the pocket of the binding site occurs with the nitrogen atom in the pentene ring of the indole structure of the triptan and the amino acid Ser352.

Dehydrogenation of paraffins and olefins - paraffins such as n-pentane and isopentane can be converted to pentene and isoprene using chromium (III) oxide as a catalyst at 500 C.
